Decades of Billboard chart data moved off SQL Server 7, Classic ASP and Visual FoxPro onto Azure, while the books kept getting published.
IIS still ships the Classic ASP runtime, so a twenty-five-year-old VBScript application keeps limping along — no debugger, no tests, no dependency management, and a security surface from another century. Because it never quite dies, it never gets budget, until the one person who understood it leaves.
I migrated a music-rights royalty system and a twenty-year Billboard chart archive off Classic ASP — the second one to Blazor on Azure, with the business publishing throughout. The pattern is the same every time: get the database somewhere safe first, put the new application beside the old one, and switch pages over one at a time. Where the old code has no documentation, an LLM-assisted pass with a confidence score on every record finds what the code actually does faster than reading it.
